The equation given is $y = 3x$. This is a linear equation in slope-intercept form, $y = mx + b$, where:

• $m = 3$ is the slope of the line.
• $b = 0$ is the y-intercept, meaning the line passes through the origin (0,0).

Steps to graph the line:

1. Plot the y-intercept: The y-intercept is at (0,0).
2. Use the slope: The slope $m = 3$ means that for every 1 unit increase in $x$, $y$ increases by 3 units. From the origin, go right 1 unit on the $x$-axis and then move up 3 units to the point (1,3).
3. Draw the line: After plotting these two points, draw a straight line through them.

Here are 5 related questions to consider:

1. What does the slope represent in a linear equation?
2. How would the graph change if the slope was negative, for example $y = -3x$?
3. How can you determine the slope and y-intercept from any given linear equation?
4. How do you find the equation of a line from a graph?
5. How does the equation change if the line is parallel to $y = 3x$?

Tip: A slope of 3 means the line rises 3 units vertically for every 1 unit it moves horizontally!
